Dairy Processing Pasteurization Verification Checklist [FREE PDF]

Pasteurization is the most critical CCP in dairy processing, mandated under the FDA Pasteurized Milk Ordinance (PMO) and reinforced by FSMA 21 CFR 117 preventive control requirements to eliminate pathogens including Listeria monocytogenes, Salmonella, and E. coli O157:H7. Verification that time-temperature parameters meet regulatory minimums, 161°F for 15 seconds in HTST systems, must be documented for every processing run under HACCP Codex Alimentarius Principle 6. This checklist provides dairy

Industry: Food Processing
Frequency: Daily
Estimated Time: 25-40 minutes
Role: FSQA Director
Total Items: 42
Compliance: FDA FSMA 21 CFR 117 Subpart C, FDA Pasteurized Milk Ordinance (PMO) 2019 Revision, HACCP Codex Alimentarius CAC/RCP 1-1969, GMP 21 CFR 110.80, SQF Code Edition 9 Section 11.7

Pre-Operation Equipment & Instrument Checks

Verify that all pasteurizer instrumentation and controls are functional and within calibration before processing begins.

Has the indicating thermometer been verified against a certified reference thermometer within the required accuracy tolerance (±0.5°F)?
Is the chart recorder or data logger functioning correctly and loaded with a new chart or cleared for data capture?
Has the flow diversion valve (FDV) been tested and confirmed to divert flow correctly when temperature drops below the critical limit?
Is the holding tube in good condition with no evidence of bypasses, leaks, or unauthorized modifications?
Were all gaskets, seals, and product contact surfaces inspected and confirmed free of cracks or damage prior to operation?

Incoming Milk & Raw Material Acceptance

Verify that raw milk received meets quality and safety standards before entering the pasteurization process.

Was incoming raw milk received at or below the required temperature (40°F / 4.4°C) and temperature recorded?
Were supplier certificates of analysis and antibiotic residue test results reviewed and acceptable for this milk lot?
Was an on-site antibiotic screening test (e.g., Delvo, SNAP) performed and confirmed negative before unloading?
Was the raw milk tanker seal number verified and recorded upon receipt?
Were organoleptic checks (odor, appearance) performed on incoming raw milk and results documented?

Pasteurization Process Monitoring (CCP Verification)

Document real-time monitoring and verification that pasteurization time-temperature requirements were continuously met.

Was the pasteurization temperature continuously maintained at or above the critical limit (161°F / 71.7°C for HTST) throughout the entire run?
Was the minimum holding time verified at the maximum permitted flow rate for this pasteurizer?
Did the recording thermometer chart/data confirm no temperature drops below the critical limit during production?
Was the pasteurization temperature reading recorded at the required frequency intervals during the run?
Did the raw milk side pressure remain lower than the pasteurized milk side pressure (HTST differential pressure control)?
Was the pasteurization start and end time recorded along with total volume processed?

Temperature Readings & Critical Limit Log

Record actual temperature readings at defined intervals to demonstrate continuous CCP compliance.

What was the actual indicating thermometer reading at the start of the pasteurization run?
What was the lowest temperature recorded on the chart recorder or data logger during this run?
Did the indicating thermometer reading and recording thermometer reading agree within the allowable 1°F differential?
Was the raw milk silo temperature verified and recorded within the safe holding range (≤40°F) before processing?
Was the post-pasteurization product temperature at the filler or storage tank within the required cold range (≤40°F)?

Deviation Handling & Corrective Actions

Document any process deviations that occurred and verify that corrective actions were implemented and recorded.

Did any temperature deviations (drops below critical limit) occur during this run?
If a deviation occurred, was the FDV diversion confirmed and all diverted product quarantined and labeled?
Was a corrective action report (CAR) completed and signed by the responsible supervisor for any deviations?
Was the regulatory authority (state dairy authority) notified within the required timeframe for any critical deviations?
Were root cause analysis and preventive measures documented to prevent recurrence of any identified deviation?

Post-Pasteurization Quality & Microbiological Testing

Review post-pasteurization product testing results to confirm efficacy and finished product safety.

Were post-pasteurization microbiological samples collected at the required frequency and submitted to the laboratory?
Were phosphatase test results negative, confirming adequate pasteurization was achieved?
Were coliform counts from finished product testing within the PMO limit (≤10 CFU/mL)?
Was a retain sample from this pasteurization run properly labeled, stored, and logged for the required shelf-life retention period?
Were sensory evaluation results (odor, flavor, appearance) within acceptable standards for this product type?

Pasteurizer CIP Cleaning & Sanitation Verification

Verify that Clean-In-Place (CIP) procedures were executed correctly and documented for the pasteurization system.

Was the CIP cycle completed for the pasteurizer and all associated piping before this production run?
Were CIP chemical concentrations (caustic and acid wash) verified and within the validated range for this run?
Were CIP cycle temperatures, flow rates, and contact times within the validated parameters and recorded?
Were post-CIP rinse water results verified (e.g., pH, conductivity, or microbiological) before resuming production?
Was the CIP record reviewed and signed by the authorized sanitation supervisor before the production start?
Were any deficiencies identified during post-CIP inspection corrected and re-verified before product contact?

Pasteurization Record Review & Authorization

Complete the final review of all pasteurization records and authorize the batch for distribution or hold for disposition.

Are all pasteurization chart records or electronic data logs complete, legible, and free of unauthorized alterations?
Have all required personnel signatures been obtained at the designated monitoring and verification points?
Has the FSQA Director or designee reviewed and approved the complete pasteurization record set for this run?
Are pasteurization records stored securely and accessible for a minimum of 2 years (or state-required retention period)?
Is the pasteurized product batch formally released for distribution with a documented release authorization?
